SPINDLE FOR CAP-SPINNING MACHINE8.

SPECIFICATION forming part of Letters Patent No. 387,245, dated August '7, 1888.

Application filed February 2, 1888. Serial No. 262,696. (No model.)

To all whom it may concern.-

Be it known that I, JoHN R. MILsoN, of Newton, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Spindles for Cap Spinning Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation of my improved spindle with the bobbin and guard or cap removed, a portion of the lifting and bolster rails being also shown in elevation; Fig. 2, a vertical longitudinal section of the same, taken lengthwise of the rails, the bobbin and guard being shown in position for use and the spindle proper represented in side elevation; Fig. 3, an enlarged vertical section taken crosswise of the rails or at right angles to the plane of the section in Fig. 2, the spindle proper being shown in side elevation and broken off and the bobbin and guard removed; Fig. 4, a hori zontal section taken on line xx in Fig. 3, certain parts being shown in plan View; Fig. 5, a side elevation of the guard or cap detached; Fig. 6, a bottom plan view of the bobbin, and Fig. 7 a top plan view of the absorbent pack ing-ring.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates more especially to the class of copspindles employed in the manufacture of worsted fabrics; and it consists in certain novel features hereinafter set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the spindle proper, B the bolster-rail, and G the liftingrail. A step, D, is secured vertically in the bolster-rail by a screw, (2, said step being provided with a screw-threaded hole, a, in its bottom and enlarged at its top to form an annular oil-cup, b, which rests on said rail. The walls of the step rise above the bottom of said cup and are provided with holes or ductsf, through which the oil passes from the bottom of the cup into the chamber 9 in the body of the step. The cup is also provided with an opening, it, in its top, through which it may be filled.

The lower end of the spindle proper, A, is screw-threaded, as shown atj, and fitted into a screw-threaded hole, a, in the bottom of the step D. It is also squared, as shown at k, to receive a wrench by which the spindle may be turned,and thereby adjusted vertically in said step. A cylindrical boss, 2', is formed on the lower portion of the spindle proper,which fits tightly in the step D, a packing-ring, m, be ing placed around the spindle below said boss,

to prevent the escape of the oil should any pass the boss from the chamber g. An absorb ent packing ring, 1), composed of felt or similar material, is placed around the spindle proper at the upper end of the chamber 9 and above the ductsf, said ring being kept in position by the upper portion of the step D, and a space, q, being left between its ends, which serves as 'a vent for said chamber.

A long tubular drivingsleeve, E, is disposed on the spindle proper, said sleeve having two vertical grooves, 1', cut in its periphery to receive the inner ends of coupling or driving pins, as hereinafter described.

A whirl or pulley, F, is secured to the lower portion of the sleeve E slightly above the top of the cup b, said pulley being provided with an annular projection, t, which extends downwardly into said cup and rests on the top of the body of the step D, which forms a bearing therefor, said sleeve being so adjusted with respect to said pulley that its lower end will be in contact or nearly in contact with the absorbent packing-ring when in use.

A long tubular bobbin-sleeve, G, is fitted to slide on the drivingsleeve E, said bobbinsleeve being provided at its lower end with an annular base-plate, H, on which the bobbin or spool I rests, and said plate provided with upwardly-projecting driving studs 1;, which engage recesses or slots to in the head of the bobbin when mounted thereon. The plate H is secured to the bobbin-sleeve G by pins 26,

which extend into the grooves r in the driving-sleeve E, and thus subserve as driving or coupling pins.

An annular socket, z, is cut in the liftingrail 0 around the driving-sleeve E, and fitted into this socket there is an inverted-cup-shaped cap, J, provided with air-holes 3 in its sides and a hole in its bottom, through which the spindle proper and sleeve E pass.

The plate H rests on the cap J and is provided on its lowerside with an annular flange, 24, which extends downwardly into said cap, said flange serving to center the cap in the socket z and keep it out of contact with the sleeve E.

An absorbent ring, K, composed of felt or analogous material,is placed around the sleeve E within the cap J, said ring serving to absorb the surplus oil, if any, taken up by the revolving sleeves and enable it to be reused in lubricating said sleeves.

A guide-sleeve, L, is rigidly secured by a rivet, 25, to the upper portion of the spindle A, said sleeve serving to prevent undue vibrations of the bobbin-sleeve G, which is fitted to slide freely thereon. the spindle proper is tapered, as shown at 27, and enters a corresponding hole in the top of the thimble-shaped guard or cap M, the guard being detachable from the spindle and of sufficient size to freely receive the bobbin I. The upper end of the guidesleeve L is provided with an annular flange, 28, for preventing the bobbin-sleeveG from being withdrawn from the spindle in doffing.

It will be obvious from the foregoing that the spindle proper, A, is stationary and that the driving-sleeve E and pulley F rotate, but do not rise or fall with the lifting-rail C; also, that the cap J, plate I-I, sleeve G, and bobbin I are raised and lowered by said liftingrail.

In the use of my improvement the oil, 30, is poured into the cup 1) until the chamber 9 is filled therewith and it stands on alevel, or nearly so, with the top of the body of the step D, thereby saturating the absorbent ring The bobbin I is then placed on the bobbinsleeve G and the cap M on the top of the spindle A, and the frame started up in the usual manner, it being understood that the pulley F is supplied with a suitable belt, whereby the sleeve E is caused to rotate as the frame runs. The frame being started up, as described, and the drivingsleeve E rotated, the bobbiusleeve G and bobbin I will also rotate, and the centrifugal action of the sleeves E and G will draw the oil upward from the chamber 9 and lubricate the parts, in a manner that will be readily understood by all conversant with such matters without a more explicit de scription.

To lubricate the inner Walls of the lower or driving sleeve, E, where they bear on the spindle A, it is necessary that air should be admitted to the cup Z) to compensate for the oil taken up by the said sleeve; but I have found that sufficient air for this purpose will The upper end of usually pass between the pulley F and cup b when the machinery is running. I have also found that in order to have the oil discharged properly from the upper end of the sleeve E to lubricate the bearing-surfaces between the sleeves G and E and G and L it is necessary to provide for the exit of air beneath the sleeve G, and hence I provide the vent or draftholes y in the cap J, which fully meet this require ment.

The grooves r in the sleeve E, for receiving the coupling or driving pins 26, subserve a very important purpose both as channels for the oil and flues for the air, enabling the sleeves to be lubricated much more effectually than it could be conveniently accomplished if they were coupled in any other manner. It is not,however,necessary to employ two grooves, one being sufficient.

The boss '5 on the spindle A serves to steady the spindle in the step D, and also as a bottom to the oil-chamber g.

The absorbent packing-ring prevents the oil from being'drawn from the chamberg with greater rapidity than is required to lubricate the parts, as it would he were said ring not used.

Having thus explained my invention, what I claim is- 1. The combination of the following instrumentalities, to wit: a bolster-rail, a spindlestep secured in said rail and provided with an oil-cup, a spindle secured in said step, adriving-sleeve mounted on said spindle above said rail and provided with a longitudinal groove or grooves and with a driving-pulley, a lifting-rail disposed above said bolster-rail, a bobbin-sleeve mounted on said driving-sleeve above the lifting-rail and provided with a plate for supporting the bobbin, means for coupling the bobbin and said plate, means for coupling the driving-sleeve and bobbin-sleeve, and a guide-sleeve secured to the upper portion of said spindle for preventing the bobbin-sleeve from vibrating, substantially as described.

2. The combination of the spindle A, the driving-sleeve E, mounted thereon and provided with the groover and pulley F, the bobbin-sleeve G, mounted on the sleeve E and provided with the plate H, coupling'pin 26, and stud 'v, the guide-sleeve L, secured to the spindle A, the cap M, mounted on said spindle, the rails B G, and an oil-cup for supplying the spindle and sleeves with oil, substantially as set forth.

3. The improved device herein described, the same consisting, essentially, ofthe spindle proper, A, step D, sleeves E G L, pulley F, plate H, stud 22, pin 26, cap J, guard M, felt K, absorbent ring p,and rails B O,constructed, combined, and arranged to operate substantially as set forth.
